Everything that you mention here as driving forces of climate change are more the fault of the ruling class at that time than boomers as a generation. What wealth everyday boomers had was more than what we had today, however the ultra-wealthy had significantly more ability to drive policy decisions than most boomers put together and they made the calls that structured the world with the climate-destroying system it has.
Also the ruling elites are the ones who took that generational wealth from this generation by their decisions as rulers. I don’t think it’s fair or accurate to blame boomers for what has happened to the planet.
Your rage is reasonable. We are living on the verge of a planet spiraling into chaos. I would just encourage you to place the blame where it really lies: ultra-wealthy ruling elites who are and have been running the planet into the ground while stealing all our time and money.
I know a few people who use it/its pronouns. While I agree that treating animals with respect is a good thing, it pronouns are not necessarily a sign of disrespect or objectification.
